Composition for treating crude fibers and textile fabrics



Patented Jan. 23, 1934 UNITED STATES COMPOSITION FOR TREATING CRUDE FIBERS AND TEXTILE FABRICS Rainer Hermann Pott, Prion near Munich, Germany, assignor to Chemische Fabrik Pott & 00., Kommandit-Gesellschaft, Dresden, Germany No Drawing. Application July 9, 1928, Serial No. 291,471, and in Germany June 15, 1921 6 Claims; (Cl. 87-5) This application forms a continuation in part of my prior copending application Serial No. 614,308, filed January 22, 1923, now U. S. Patent No. 1,750,430.

When treating textile fibers, in order to obtain spun-or woven products or other products of any kind, it is of utmost importance that the fibers be thoroughly cleansed and degreased before they are subjected to the subsequent chemical and 10 mechanical treatments.

I have now found that the eifects of the rinsing, washing and degreasing processes are greatly improved when there are added hydrogenated naphthalenes, for instance, tetrahydronaphtha-' lene or deka-hydro-naphthalene which have been made water-miscible by being mixed with small amountsof such substances as saponified fats, sulphonated fats and their neutralization products, alkylated aromatic sulpho acids, naphthenic acids and water soluble salts of such acids (each substance may be used alone or two or more substances may be admixed together.) By neutralization products of sulphonated fats, I mean water soluble salts of said fats. It is also possible to use all other emulsifying agents for fluids which per se are insoluble in water. v

It has already been proposed to improve the rinsing powers of soaps by incorporating hydrogenated naphthalenes into the same. The difference between such soaps and the compositions according to the present invention is that the latter are not soaps containing small amounts of hydrogenated naphthalenes but are hydrogenated naphthalenes which have been made water-miscible and in which the-amount of the emulsifying agent (which in a special case may be soap) used is of no importance with respect to the rinsing efiect.

Further, according to this invention, a great variety of emulsifying agents of different natures may be used. The new compositions are intended to be used in connection with the rinsing and cleansing treatment known per se, in the form of special baths, which preferably are applied before the washing or degreasing treatment proper takes place.

The compositions may, for instance, consist of the following ingredients:

Example 1 Parts by weight 3.5 1.7 89.3 5.5

Sodium salt of isopropyl-naphthalene-sulphonic acid 8 I claim:

1. A composition for treating and cleansing textile fibers comprising hydrogenated naphthalenes which have been made water-miscible by means of small amounts of sulphonated fats.

' 2. A composition for treating and cleansing textile fibers comprising hydrogenated naphthalenes which have been made water-miscible by means of small amounts of water soluble salts of sulphonated fats which are characterized by the power of emulsifying fluids which are by themselves insoluble in water.

3. A composition for treating fibers and textile materials, comprising hydrogenated naphthalenes made water-miscible by being mixed with small amounts of an emulsifying agent selected from the group consisting of sulphonated fats, alkylated aromatic sulfornc acids, and the water soluble salts of such acids.

4. A composition for treating fibers and textile materials, comprising tetra-hydro-naphthalene made water-miscible by being mixed with a small amount of an emulsifying agent selected from the group consisting of sulfonated fats, alk lated aromatic sulfonic acids, and the water soluble salts of such acids.

5. A composition for treating and cleansing textile fibers containing as initial ingredients ricinoleic acid. ammonia, a hydrogenated naphthalene and methyl-hexalin, the hydrogenated naphthalene forming more than 80% of the composition.

6. A composition for treating and cleansing textile fibers containing as initial ingredients 3.5 parts of ricinoleic acid, 1.7 parts of ammoniacal liquor having a specific gravity of 0.910, 89.3 parts 01' tetra-hydro-naphthalene and 5.5 parts of methyl-hexalin.
